<div class="sreweekly-description">
<p>What does owning your availability really mean? Brave New Geek argues that it simply means owning your design decisions. I love this quote: </p>
<blockquote><p>An SLA is not an insurance policy or a hedge against the business impact of an outage, it’s merely a refund policy.</p></blockquote>

<div class="sreweekly-description">
<p>Facebook uses configuration for many facets of its service, and they embrace &#8220;configuration as code&#8221;. They make extensive use of automated testing and canary deployments to keep things safe. </p>
